TO ALL WI-:IOM IT MAY CONCERN:

Be it known that I, Ilo'UvIs T." PYOTT,of the city and county of Philadelphia, in the Staten of-Pennsylvania, have invented a certain new and useful Improvement in Cooking-Stoves; and I do hereby declare the following to be a full,.clear, and exact description ot' theisame, referen ce being had to the accompanying drawing, which forms' part ot' this specification;

My invention relates to cooking-stoves which are provided with a movable furnace'or replace, adapted to concentrate the heat in any desiredpart of the stove. V

My movable furnace is mounted upon wheels, which are encased and protected in such 4a way as to prevent their being either clogged or injured inuse, and which it and run upon 4a V-shaped track,- Which extends forward upon the stove-hearth, so that the furnace maybe run out clear of the stove for convenience in clearing it'of unconsumcd ciuders, Svc., and for making the fire.

Y' I also employ an automatic damper, adapted to be operated by the movement of the furnace, and. serving` to properly direct the air and heat, as will be hereafter explained.

The drawing represents a vertical longitudinal section ofa cooking-stove embodying my improvements. S may represent'the external walls of the stove, O the oven, and I-I a movable heartb-plate, covering the ,ashpit I. A represents thelfurnace,moun ted upon wheels B B, which are ttedvnto recesses or casings in the cast-iron ends oi' the furnace, so as to protect them from injury or from being choked' or clogged with ashes or other matter. Two wheels, B B,'are thus .'ppliedv toeach end ofthe furnace, arid they run upon V-shaped tracks,-G, which serve the purpose of guides without being liable to 'be obstructed with ashes. Thetraeks C extend from the baci; of the stove `to the extreme fron-t of the hearth, so as to aiford the furnace threedistinct adjustments: iirst, beneath the boiler-holes IF, as represented in the drawing; second, back beneath theoven O, as represented indotted lines; and, third, forward upon the hearth, for the purpose of clearing the furnace, or making or rcplenisliing the lire. I f y Y When the furnace is to be run'out to its forward position, this i'rnt doors, G', ofthe stove are thrown open, and the hearth-plate II is either slidden forward or removed,V D represents a piveteddamper, extending completely across the stove, and forward atene end, with a downward-projecting arm, d, through which thefdamper is moved by a tappet,`-a, (shown by dotted linea) which projects from one end of the furnace. I representen secondary damper', to close the lue in, the rearot' the oven, when the furnace is in its central position beneath the front boiler-holes, as shown inthe drawing.-v 'E represents a-'gravitating-plate, 'extending from side to .side

of the stove, andformed at its front edge `to fit over. the front bar of the furnace, so as to secure the furnace (when in its central position) against accidental displacement, in raking the fire, for example. 'The said plate E also serves to ,prevent the draught passingA over the top of the furnace without going throughthe fire. An external handle, e, is employed' to lift thetretainin --plate clear of the-furnace when the latter is to be moved.

' The plate E may bereadily adaptedto autoinatically catch the upper bar of the furnace as it comesunder it .from either direction, and retain' it until the handle e'is' depressed.'

When the furnace is run bach-the tappeti a carries the levend back with it, Aturning the damper forward 'until the latter passes the centre, whenitfalls to the position shown by dotted lines, so as to c losethe passage above the front of the furnace. vThe damper I being 'then opened, all. the draught willV be compelled to pass through the furnace andupin'front and behind the oven. 4 l l Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-' 1; The combined furnace and truck A, mounted upon boxed or encasedwheels B B, as described and for the purpose specified.V

v 211111 combination with the foregoing, I further claim the V-shaped rails, extending' from the rear of the stoveto the front of the hearth, as and for purposes explained.

y' 3. I claim the-automatic division-plate or damper D operated bythe miotionoftthe furnace, as 'and for the purposes described.

. 4. I .further claim the detainingQplateE, in combination with the shifting furnace A, vin the manner described. l Y v i To the above speciiication of my cooking-stove, I have signed my hand, this 25th day of January, A. D..1868.
